New Studies Show Air Purifier Can Help Improve Student Performance

Discover how investing in an air purifier can actually boost academic performance for students

By Lee Min | Apr 26, 2024 | 9:30 am GMT +8

With intense competition in schools and workplaces nowadays, it's no surprise that education has become of utmost importance and, thus, the main priority for a lot of students. The need for having good grades to pave way for a brighter future has never been greater. However, there is a lack of focus on optimizing the environment in which students conduct their learning, be it their classroom or their home.

Many environmental factors can influence how well a student performs academically including commute distance, temperature, noise levels, and air quality. Recent studies have shown a strong correlation between indoor air quality and students' academic performance. So why is indoor air quality such a crucial part of any study environment, and why is an air purifier an excellent investment to improve students' academic performance? Read on to learn more.

On average, Singaporean students spend 50 hours studying per week almost entirely indoors... Where poor indoor air quality has been researched to negatively impact their performance.

Poor indoor air quality and student performance

When it comes to the adverse effects of poor indoor air quality, students are more vulnerable than adults. Their respiratory, immunity, and nervous system is not matured yet, making them more susceptible to various health symptoms, diseases and long-term health issues when exposed to harmful indoor air pollutants, which can severely hinder their performance at school. Numerous studies including this scientific study have shown that exposure to air pollutants can lead to lower academic test scores. Indoors, the most common air pollutants that can impact students' academic performance include particulate matter PM2.5, volatile organic compounds (VOCs), and indoor allergens. Here's why:

PM2.5 and student performance

PM2.5 is one of the most dangerous air pollutants that pose serious health issues due to their extremely small size, and thus ability to gain access to the respiratory system, heart, brain, and bloodstream.

Recent scientific studies demonstrate that exposure to PM2.5 can lead to increased stress levels in students and, in some cases, depression. Additionally, research has shown high levels of stress can reduce academic performance, decrease students' motivation to complete school work, leading to increased student dropout rate.

More importantly, based on recent studies, inhalation exposure to PM2.5 can lead to an increased risk of lower cognitive function among children and adolescents, which may result in students having greater difficulties understanding subjects, leading to poor exam performances. Case in point, research suggests students exposed to PM2.5 show worsened performance on mathematical subjects' exams.

Effects of VOCs & indoor allergens

VOCs, chemicals that vaporize at room temperature, can be harmful to health if inhaled. VOCs are emitted from a lot of household products such as cleaners, air fresheners, personal care products, cooking oils, paints, solvents, markers, glues, and more. Research shows that exposure to high levels of VOCs can cause irritations to the eyes, nose, and throat, headache, fatigue, and difficulty concentrating, all of which can negatively impact students' academic performance.

Also, exposure to indoor allergens such as dust mites, pollen, mold spores, pet dander, and tobacco smoke can cause a variety of allergies, inflammation, and respiratory diseases, symptoms of which include asthma, sneezing, blocked or runny nose, postnasal drip, itchy watery eyes, and sore throat. The discomfort and irritation from these symptoms can cause sleep disturbances and poor sleep quality. Furthermore, research suggests poor sleep quality correlates to lower school grades in students.

How air purifier improves student performance

Using a high-quality air purifier with an advanced filtration system can capture all indoor air pollutants including PM2.5, VOCs, and allergens such as dust mites, pollen, mold spores, smoke, pet dander, smelly odors and much more. This reduction in harmful air pollutants and allergens can help improve students academic performance by reducing stress levels, relieving discomfort from allergy symptoms, and improving sleep quality, immune system, and overall health.

Reduce stress levels

Research has shown that indoor air purification results in a reduction in stress levels, which greatly benefits students in their academic performance. Moreover, the use of air purifiers with a HEPA (high efficiency particulate air) filter helps effectively reduce airborne PM2.5 levels to protect against adverse health effects of air pollution including impaired cognitive function, high blood pressure, inflammation, and air pollution-induced stress.

Reduce discomfort from allergy symptoms

High-quality air purifiers with advanced HEPA filtration systems are proven to relieve not only indoor allergy symptoms but also asthma and cardiovascular diseases by reducing concentration of indoor air pollutants including PM2.5 and VOCs, and allergens. This reduction in the harmful air pollutants relieves discomfort and irritations from symptoms, improving student's concentration and academic performance.

Improves sleep quality

By using high-quality air purifiers, unpleasant nighttime allergy symptoms such as nasal congestion, coughing, and asthma are reduced since airborne pollutants and allergens are minimized. As a result, there will be fewer sleep disturbances, and the body can get in a deeper, more high-quality sleep. Moreover, air purifiers can also act as a white noise machine which can reduce the time it takes to fall asleep by almost 40%. Better and longer sleep results in improved concentration, and better grades.
